(Summary description)        Powder materials, especially nano-materials (nano-materials refer to particles or structures, crystals or nano-composites with a nanometer length ranging from 1 to 100 nm). A very important feature is the surface effect. The surface effect of powder materials is the powder The ratio of the surface atom number of the bulk particles increases greatly with the smaller the size of the powder particles. After the powder plasma surface treatment equipment is processed, the surface energy of the particles can be increased, that is, the surface tension also increases, thereby causing changes in the properties of the powder materials. . Powder plasma surface treatment equipment         As the particle size decreases, the specific surface area of ​​the particles increases rapidly and is very unstable. Therefore, these atoms are easily combined with other atoms and stabilized. They have high chemical reaction activity. For example, metal nanoparticles will burn in the air. Some oxide powder particles are exposed to the atmosphere to adsorb gases and so on.         The main problem in the application of powder materials for powder plasma surface treatment equipment is to improve the surface effect of the powder. Improve the dispersibility and surface indirectness of the powder. For example, it can be seen that the smaller the nano-particle size, the more obvious the nano-specific function. The smaller the particle size of the powder, the more serious the agglomeration of particles. The agglomerates may reach sub-micron or even micron levels, which seriously affects the application of nano additives in fibers, especially the spinnability of the powder particle/fiber composite system. The use of powder plasma surface treatment equipment can realize the conventional performance of particles, which fully reflects the special functions of the powder particle/fiber composite system.
